Answer:
Surface area of the cone = 360π in²
Step-by-step explanation:
Formula for the surface area of a cone is,
Surface area = πr(r + l)
Here 'r' = radius of the circular base of the cone
l = Lateral height of the cone
Now we substitute the values in the formula from the figure attached,
Surface area = π(10)(10 + 26)
= 360π in²
Therefore, surface area of the cone will be 360π in².
